In the title compound, C 10 H 8 N 8 ΓC 8 H 6 O 4 , both acid and base molecules (A:B) have twofold crystallographic symmetry. One-dimensional zigzag chains of rings form as (AΓ Γ ΓBΓ Γ Γ) n through O-HΓ Γ ΓN and C-HΓ Γ ΓO C interactions; further association of B (with A) along the a axis via bifurca
All interatomic distances in the title compound, C~5~H~7~N~3~O~2~S, are normal. The 1,2,4-triazoline ring is planar and it is inclined at 78.61β (7)Β° to the planar acetic acid group. The molecules of the title compound are connected __via__ OβH...N hydrogen bonds into zigzag chains along the [101] di
The title compound, C 8 H 2 Cl 4 O 4 , was synthesized by the reaction of 2,3,5,6-tetrachlorobenzene-1,4-dicarbonitrile and sulfuric acid. The molecule is located across an inversion center. The carboxyl group is tilted with respect to the benzene ring by an angle of 72.42 (7) . Intermolecular O-HΓ
